drawing, wherein similar reference characters have been employed todenote corresponding parts and wherein Figure l is an illustration of ahuman body provided with the gyves. Fig. 2 is a frag mental face view ofthe gyve or of the lock proper for the joint of the limb. Fig. 3 is aview of the device illustrated in Fig. 2 showing the near face cut away.Fig. 11i is a sectional view taken on the line .t-ll of Fig. 3. Fig. 5is a perspective view of one of the teeth of the dogs or pawls.

ln carrying out the present invention, reference being had to thaccompanying drawing, there is provided a novel form of lock designatedby the numeral G which is adapted to be disposed at the joint of thelimb, and which may be conveniently termed or denominated the joint lockor limb lock. its illustrated in l, the lock (S is disposed at the kneejoint of the lower limb, and has the sections 7 and 8 secured to therespective parts thereof, the parts of the casing of the lock beingadapted to rotate. rThe section 7 is adapted to extend along the thighor femur bone of the wearer while the section 8 is adapted to extendalong the lower limb proper' or the calf to the ankle. A section 9 ispivoted to the upper end of the section 7 and is adapted to extend alongthe hip of the wearer or above the waist line. Fig. l also illustrates alock G applied to the elbow of the arm, and having the respectivesections 7 and S attached to the parts of the casing of the lock. rl`hesection 7 is adapted to extend along the upper section or humerus, whilethe section 8 is adapted to extend along the forearm to the wrist.

From the foregoing, it will be manifest, without further explanation,that the present appliance may be attached to either the upper or lowerlimbs with equal propriety, and it will therefore only be necessary todescribe one of the locks in detail, the two locks being precisely thesame, with the exception of the respective sections attached to theparts of the casing of the lock which must be of suitable length toaccommodate the upper and lower limbs, as will be apparent.

Upon the respective sections S. 7, 9. 8 and 7, there are adjustablymounted the locts l0, 10b, 10C, 10d, and 10e, and to the locks are CINattached the respective ends of chains or flexible members 11, 11b, 11C,11d and 11e. rllhese locks iorm the subject matter of a co pendingapplication, Serial Number 749,002, filed Feb. 17, 1913, and need not bedescribed or illustrated in detail in the present application. rThelocks 10, 10b, 10, 10d and 10 are adjustably mounted on the respectivesections and are designed to lock at various adjusted positions on thesections as well as locking the free ends of the chains or flexiblemembers. These chains or flexible members are preferably covered withrubber tubing or the like, so as to protect the wearer from being chafedor otherwise injured. rihus, the chains or bands 11, 11b, and 11C areadapted to encompass the ankle, the lower portion of the thigh, and thewrist, respectively, so as to hold the sections 7, S and 9 in operativeposition, the said sections being capable of swinging movements topermit the movement of the lower limb. In a like manner, chains or bands11d and 11e are adapted to encompass the wrist and liumerus,respectively, so that the respective sections will move with the membersof the arm. The locks 10, 10b, 10C, 10(1 and 10e are adjustably mountedon the respective sections as above indicated, in order that the chainsor flexible members may be properly positioned to most effectively holdthe gyves in position upon the limbs.

Coming specifically to the joint or limb lock, the same embodies acasing comprising two rotatable parts, or an inner cap 12 and an outercap 13 telescoping thereover. The respective sections 8 and 7 have theirends riveted or otherwise secured to the faces of the parts 12 and 13 ofthe casing, in order that when the sections are swung relative to eachother, the parts of the casing will be rotated upon each other.

TWithin the part or cap 12 there is fitted a ring or annulus 14, thesaine fitting snugly within the flange or rim of the part 12. T heflange of the part 12 is undercut slightly, as seen in Fig. 1, and theperiphery of the ring 1e is slightly beveled to lit within the under`cut portion so as to retain the ring into position, and the ring is alsopreferably constructed of four sections or is split at points throughoutits length. The ring 14 or two diametrical opposed sections thereof, areeach provided with a series of ratchet teeth 15, which face in theproper direction in order that the lock will operate in mannerhereinafter described.

A guide 16 is disposed concentrically within or between the parts of thecasing, the same being circular at one side and fitting within anopening 1'? provided in the part 12. An annular rabbet 18 is providedaround the opening 17, in which is seated a disk or plate 19. A pair ofrivets or securing members 2O are passed through the disk 19, guide 16and the face or part 18 of the casing, in order to secure the parts orfaces of the casing together and in order to secure the guide 16 to theface or part 13 of the case.

The guide 16 is provided with the parallel edges 21 within the casing,and a pair of oppositely disposed U-shaped pawls or dogs have their armsstraddling the guide 16 and working' snugly against the edges 21 so thatthe pawls or dogs are constrained to slide radially or on a diainetricalline. Each of the pawls or dogs 22 is preferably stamped from sheetmetaland embodies a long arm and a short arm, the long and short arms of onepawl overlapping the short and long arms of the other pawl. A leafspring' 23 is secured to each pawl 22 adjoining the butt end of the longarm and has its free end bearino` against the free end of the long armof the other pawl, the springs 23 tending to separate or spread thepawls so as to force them into engagement with the ring 14. Each of thepawls 22 is also provided with a tooth 24 at its intermediate point, theteeth 24e having dovetailed projection 25 engaging the pawls. T he pawlsare of a combined thickness so as to i'it snugly between the faces ofthe casing and the teeth 2li are also of a thickness to work snuglywithin the faces of the casing, while the dovetailed projections 25 areapproximately flush with the faces of the re spective pawls.

The guide 16 is provided between the rivets 2O with a lateral recess 26for the reception of a suitable key, and a linger 27 stands centrallywithin the recess 26 and over which the socket of the key may be en*gaged so that the key may swing on the finger 27 as a pivot. The face 13of the casing is provided with a key-hole opening 29 thro-ugh which thekey may be projected or introduced, the key-hole opening 29 registeringwith the recess 26. The long arms of the pawls are provided with notches2S in their inner edges and at the ends of the recess 26, so that whenthe key is inserted into the recess, the ends thereof may engage thenotches 28 in order that when the key is turned properly or counterclockwise as seen in Fig. 3, the pawls will be forced together againstthe tensions of the springs so as to retract them from the ring 14.

1n the use of the gyve, it being understood that the sections which areattached to the parts of the casino` have been properly applied to themembers of the limb, the pawls 22 are adapted to normally stand betweenthe ratcnet teeth 15, so as to permit of the limited movements of themembers of the limb without locking them. It will be noted that as therespective sections are swung relative to each other, the ratchet teeth15 will be carried or moved with the part 12 spective paWls at the buttends of the long arms and bearing against the tree ends otl the longarms of the opposite pawls.
